THE BASILICA OF PEACE, HIPPO.
Augustine had his chair (his cathedra) in his church at Hippo, a building called a cathedral because of that fact.
It was also called a basilica because of its regional importance and its considerable size (37m by 18m, or 110 feet by 54 feet) in the North African setting.
In the ruins of the town of Hippo today, the site of the basilica is easily located.
The continuing presence of the bottom parts of walls and columns, plus some mosaic flooring, allow an accurate description of what the basilica must have been like when Augustine was using it.
